Provided are a control method and system for a hybrid electric vehicle after a battery failure and a hybrid electric vehicle. The control method includes: after monitoring that a failure occurs in a power battery, judging whether the failure is a specific type of failure or not, the specific type of failure being a battery failure under which a motor of a hybrid electric vehicle is capable of conducting voltage control (S402); if so, setting a relay of the power battery to be disengaged after a preset time (S404); before the relay is disengaged, coordinating and controlling the power battery, an engine, a transmission and the motor of the hybrid electric vehicle to enable operation states thereof to meet a preset voltage control entering condition (S406); and controlling the motor to enter into a voltage control mode (S408). The motor is allowed to enter into voltage control smoothly and operate stably, thus avoiding problems of overtemperature of a battery, serious voltage fluctuation and the like caused by direct voltage control on the motor after a power battery failure.
